This invention relates to new and useful improvements in amechanical collecting container.

This invention relates to similar subject matter as that disclosed in my Patent No. 1,740,116, granted on December 17th, 1929.

The invention has for an object the provision of a device of the class mentioned which is of simple durable construction, depend-- able in use and efiicient in action, and which can be manufactured and sold at a reasonable cost.

The invention proposes the construction of a device of the class mentioned which requires the services of few men to operate it and accomplishes the work of a larger quantity-of men working on prior equipment.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure Fig. l is a plan view of a device constructed according to my invention and applied upon a truck. 1

Fig. 2 is a side elevational view of the device, per se.

Fig. 3 is a fragmentary vertical sectional view taken on the line 3-3 of Fig. 1.

Fig. 4. is a fragmentary vertical sectional view taken on the line 4-4 of Fig. 1.

The invention consists of a container 10 in combination with a truck body 11, said container being open at the top 12 and at the bottom 13 and having its rear side 14 pivotally connected at its top on adjacent sides 15 of the container so as to be movable to a horizontal position to open the rear of the container, coacting means on the truck body and container for raising and lowering the container so that in the raised position the truck may travel, and in the lowered position the container may encircle a pile of snow, coal or other articles upon the ground, a. frame 16 attached on the rear side 14 of said container, a slide 17 transversely across the bottom of the container and movable onto said frame 16 for opening the bottom of the container, and means for moving the slide from one to the other of said positions.

The truck body 10 is shown mounted upon the chassis 18 of a conventional motor-vehicle. The container 10 merely consists of four vertical sides, that is, the rear side 14, the sides 15 and front side 19. The front side 19 is rigidly connected with the sides 15. As before stated, the rear side 14 is pivotally connected so that it may pivot. The pivotal connection is accomplished by pins 20 arranged between projections 21 from the sides 15 and projections 22 from the rear side 15. In Fig. 2 the dot and dash lines 23 indicate the position of the side 14 when it assumes its horizontal condition.

The means on the truck body and the container for raising and lowering the container consists in vertical tracks 24 arranged on opposite sides of the container and coacting with vertical tracks 25 on opposite sides of the truck body. In addition, vertical racks 26 are attached upon the sides 15 of the container and are engaged by gears 27 supported upon stud shafts 28 rotatively mounted within the truck body. A cable 29 is wound around one of the stud shafts 28 in one direction and another cable 30 is wound around the other stud shaft 28 in the opposite direction, and these cables are intended for connection to some source of power so that one or the other may be drawn to cause rotations of the gears 27 for -moving the container up or down. The power preferably should be a drum connected with the engin of the vehicle 18.

The frame 16 consists of opposite frame sections held inspaced positions by a tie rod 32. Tracks 33 are arranged upon the frame 16 and the container 10 and are aligned with each other when the frame 16 is in its lowered position. The rear side 14 of the container is shorter than the other sides so that the slide 95 17 may move across fromthe frame to the container.

The means for moving the slide 17 from a position on the frame to a position on the container, or vice versa consists ofcables 34 .00

attached to the rear of the slide and passing thru apertures in the frame 16 to the extepower similar to that used for the cables 34.

- 37 upon the frame 16. Cables 38 connect The frame 16 may be latched in the lowered position, as shown in full lines in Fig. 2, by hook elements 36 pivotally mounted on the container and engageable with eye elements with the hook 36 and may extend to the vicinity of the driver seat so that the driver may draw upon these cables for disengaging the hooks. A cable 39 is attached upon the tie rod 32 and is for connection with a drum connected with the motor of the vehicle or other source of power so that the frame 16 may be mechanically raised to the position indicated in dot and dash lines in Fig. 2.

In operation, and in the normal position of the truck, the container 10 is in its raised position and the frame 16 in its lower position as shown in Fig. 1. For removing a pile of material, the frame 16 is raised and the container 19 lowered until it nearly touches the ground. The truck is then backed up so that the pile of material is encircled by the sides 15 and 19 of the container. The frame 16 is next lowered and the slide 17 operated for moving from this position on the frame to its position on the container, so as to divide off the pile or other material. Next the container 19 is raised to its normal position within the truck and the truck may proceed along its way.

While I have illustrated and described my invention with some degree of particularity, I realize that in practice various alterations therein may be made. I therefore reserve the right and privilege of changing the form of the details of construction or otherwise altering the arrangement of the correlated parts without departing from the spirit or the scope of the appended claims.

Having thus described my invention, what I claim as new, anddesire to secure by United States Letters Patent is 1. In combination with a truck body, a container opened at the top and bottom and having its rear side pivotally connected at the top on adjacent sides so as to be movable to a horizontal position to open the rear of the container, coacting means on the truck body and container for raising and lowering the container so that in the raised position the truck may traveland in the lowered position the container may encircle a pile of coal, snow or other material upon the ground, a frame attached on the rear side of said conments only.

tainer, a slide transversely across the bottom of the container and movable onto said frame for opening the bottom of the container, and means for moving the slide from or other material upon the ground, a frame attached on the rear side of said container, a slide transversely across the bottom. of the container and movable onto said frame for opening the bottom of the container, and means for moving the slide from one to the other of said positions, said coacting means on the truck body .and container for raising and lowering the container including a vertical rack attached on the container, a gear rotatively supported on the truck body and meshing with said rack, and means for supporting said conta ner for vertlcal move- Signed at New York in the countyof New York and State of New York this 2nd day of April, A.
